Azetidine, pyrrolidine and hexamethyleneimine at 170 K [PDF]

open access: yesActa Crystallographica Section C Crystal Structure Communications, 2008
The crystal structures of the cyclic amines azetidine (C(3)H(7)N), pyrrolidine (C(4)H(9)N) and hexamethyleneimine (homopiperidine, C(6)H(13)N), of the series (CH(2))(n)NH, with n = 3, 4 and 6, respectively, have been determined at 170 K, following in situ crystallization from the melt.

Methyl 2-Amino-4-[1-(tert-butoxycarbonyl)azetidin-3-yl]-1,3-selenazole-5-carboxylate

open access: yesMolbank, 2021
Methyl 2-amino-4-[1-(tert-butoxycarbonyl)azetidin-3-yl]-1,3-selenazole-5-carboxylate as a newly functionalized heterocyclic amino acid was obtained via [3+2] cycloaddition. The structure of the novel 1,3-selenazole was unequivocally confirmed by detailed

Azetidines. II. Some Functional Derivatives of Azetidines [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1967
Abstract The sodium methoxide-catalyzed cyclization of methyl α-tosylamino-γ-chlorobutyrate gave methyl 1-tosylazetidine-2-carboxylate, which was then converted to the corresponding carboxylic acid and carbinol. 1-Acetyl-2,2,4,4-tetramethylazetidine-3-carboxylic acid was prepared by the photolysis of 1-acetyl-4-diazo-2,2,5,5 ...

Stereoselective Access to Azetidine-Based α-Aminoacids and Applications to Small Peptides Synthesis [PDF]

open access: yes, 2020
Recent progress on four-membered ring building blocks has led us to investigate the formation of non-natural azetidine-based amino acids (Aze). A simple organometallic route was developed to access unsaturated carboxylic acids, which were further engaged
